It's estimated that over 120,000 people are blind in Cambodia, half of those from cataracts.
Cataracts mainly affect the elderly, causing eventual blindness due to clouding of the clear lens that enables the eye to focus, it is a long term degenerative process but it can be treated.
Sadly also, there are lot of people coming in their mid-20s who are blind from vitamin A deficiency, who could be refered to as being Pol Pot's children, because they had a diet of rice gruel, totally deficient in fresh fruit and vegetables, meat, and their eyes were destroyed.
''much has been achieved in recent years. Prior to 1995, there were no doctors in Cambodia that had any training in the treatment of eye disorders and diseases; so if you were blind, you remained so. Since then, the government has set up the National Sub Committee for Prevention of Blindness (now known as the National Eye Health Program), supported by a number of local and international non-government organisations''. ''there is a patient subsidy system in place to ensure the poorest of the poor have access to quality eye care services. Over time, as trust in the public eye health system grows, more people will use the services and enable a tiered pricing system, whereby wealthier paying patients subsidise the treatment of poorer patients''.FHF Foundation
